Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.
This occurs when the two numbers are prime. Prime numbers have only two factors, 1 and the value of the number itself. Therefore, two dofferent prime numbers would share no common factors other than 1.
Hope this helps!
The answer is 0.019 i think
1) First is an odd function because f(-x)=-f(x)
3) 3d is an even function because f(-x)=f(x)
2) 2d looks like sin function and it is also odd.
